Looks like we're coming to the end of the awesome HOTS cinematics and content releases...

We’re constantly changing and evolving not only our games, but how we support and grow them. This evolution is vital to our ability to continue doing what we love to do—making great games—and it’s what makes Blizzard, Blizzard.

Over the past several years, the work of evaluating our development processes and making hard decisions has led to new games and other products that we’re proud of. We now have more live games and unannounced projects than at any point in the company’s history. We’re also at a point where we need to take some of our talented developers and bring their skills to other projects. As a result, we’ve made the difficult decision to shift some developers from Heroes of the Storm to other teams, and we’re excited to see the passion, knowledge, and experience that they’ll bring to those projects. This isn’t the first time we’ve had to make tough choices like this. Games like Diablo II, World of Warcraft, StarCraft II, Overwatch, and more would not exist had we not made similar decisions in the past.

Despite the change, Heroes of the Storm remains our love letter to Blizzard’s worlds and characters. We’ll continue actively supporting the game with new heroes, themed events, and other content that our community loves, though the cadence will change. Ultimately, we’re setting up the game for long-term sustainability. We’re so grateful for the support the community has shown from the beginning, and the development team will continue to support Heroes with the same passion, dedication, and creativity that has made the game such a unique experience.

We’ve also evaluated our plans around Heroes esports—after looking at all of our priorities and options in light of the change with the game, the Heroes Global Championship and Heroes of the Dorm will not return in 2019. This was another very difficult decision for us to make. The love that the community has for these programs is deeply felt by everyone who works on them, but we ultimately feel this is the right decision versus moving forward in a way that would not meet the standards that players and fans have come to expect.

While we don’t make these decisions lightly, we do look to the future excited about what the decisions will mean for our other live games and all the projects we have in the works. We appreciate all of our hard-working developers and everyone in the Blizzard community, and look forward to sharing many more epic gaming experiences with you in the future.

Both that and also the game doesn't seem to be all that profitable if they're scaling back and putting the game into maintenance mode. There are 11 more spots on the character select screen that are still blank... my theory is that they have just 11 more characters to roll out before a final balance patch and then they may do the odd event/cosmetic release.
